摘要

在本文中，我们重新审视了测试机器嵌入的概念，并提出了一种特定的测试机器架构:细胞扫描。这种架构提供了优于传统扫描和循环扫描的优点。与传统扫描相比，元胞扫描以确定性生成的向量缩短了所需的测试时间。与循环扫描相比，蜂窝扫描对硬件的要求更少，对状态覆盖没有限制，并且可以显著提高顺序逻辑的随机模式可测试性。

Cellular Scan Revisited

In this paper, we re-examine the concept of test machine embedding and present a specific test machine architecture: cellular scan. This architecture offers advantages both over traditional scan as well as circular scan. Compared to traditional scan, cellular scan shortens required test time with vectors generated deterministically. Compared to circular scan, cellular scan requires less hardware, has no limitations on state coverage, and can significantly improve random pattern testability of sequential logic.
